Finished with clear shellac, I believe. Ive used it for so long I’m not certain what I used to finish it. Satin smooth feel, refretted with jumbo stainless frets, and either gotoh or kluson tuners, once again it’s been so long I’m not sure what I installed. Bone nut. The black spot on the side is from when I stained a guitar and stupidly left the neck on and didn’t tape it off correctly. If you’re looking for a fat neck for your Richie Kotzen or G.E. Smith build, this neck is quite substantial. I used it for years, had it refretted and used it some more. Fell in love with a different guitar and now it was just sitting. So up on the auction block it goes, away to someone who will play it. Thanks for looking. Less than 20 feedback message me BEFORE you bid. No reserve! USA only shipping.
